Abstract Resume

Background:To identify risk population groups and what affect the harmful effects of health in childhood and adolescence are important initiatives to develop relevant interventions on
the control chronicle diseases in adult life . As such, the aim of this study was to analyze the behavior of the variables related to growth, development, and PFRH, of children and adolescents during
four years (2012, 2013, 2014 e 2015).
Methods:This study was approved by the Committee of Ethics of Universidade Federal de São Paulo, under appraisal no. CEP 234/11, and informed written consent was obtained from all
volunteers before starting the study. The sample was composed by 27 students (14 boys and 13girls) from 8 to 15 years old. The variables investigated were: body mass [BM (kg)], height [H (m)], body
mass index [BMI (kg/m²)], percent of body fat (%BF), flexibility [Flex (cm)], aerobic fitness [AF (m)], speed [S (m/s)], lower limbs strength [LLS (cm)], upper limbs strength [ULS (kg/f)] e abdominal
[ABD (rep)]. The repeated measures test and post hoc of Bonferroni were used for analysis and comparison during four years of the study.
Results:There has been a significant increase of BM for the girls from 2012 to 2013, 2014 and 2015 (p=0,00), and from 2013 to 2014 and 2015 (p=0,046 e 0,007). For the boys, the
increase of BM happened from the first to the following assessments (p=0,00).The height had a significant increase for the girls from 2012 to 2013, 2014 and 2015 (p= 0,00; 0,00; 0,029); since for the
boys this increase was found from 2012 to 2014 and 2015 (p=0,00). Regarding the BMI, the results were quite similar to those found for BM. No significant difference was found for the variables %BF,
ABD and S in both genders. With respect to physical performance variables, the Flex showed a significant increase from 2012 to 2013 and 2014 (p=0,057; 0,025) for the girls, and for the boys there is
no changes. For AF, the girls didn´t showed significant difference, since the boys showed difference from 2012 to 2014 (p=0,008). For LLS, the girls presented a difference from 2012 to 2013 and 2015
(p=0,00; 0,014), and from 2013 to 2014 and 2015 (p=0,00); while in the male gender was found a difference from 2012 to 2013, 2014 and 2015 (p=0,016;0,016;0,00) and from 2013 to 2014 (p=0,004). As a
last variable studied, the ULS showed significant difference from 2012 to 2015 for girls (p=0,004), and for the boys from 2012 to 2014 and 2015 (p=0,005;0,00), from 2013 to 2014 and 2015
(p=0,014;0,00), and from 2014 to 2015 (p=0,005).
Conclusions:Through the results obtained, it can be verify that the subjects increased the BM and H, but no difference was found in %BF. For physical performance variables, the more
significant increases happened when the strength generated was not depended from actions with much displacement.
